After upgrading from Rancher 1.2.0 to 1.2.2 yesterday. Today, I discovered that Rancher shows the host as ‘Disconnected’. I couldn’t figure out why this was happening, so I tried to re-register the host with a new Rancher Agent. However, the Rancher Agent is showing some sort of problem when trying to re-register itself. What could cause this problem? I start the Rancher Agent, and it exits fairly quickly. I see that the rancher-agent bootstrap container doesn’t fire off any new containers from the rancher/agent image: ``` [root@docker01 ~]# docker run -d --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.1.2 https://rancher01.example.org/v1/scripts/blahblah1:12345blah:blahblah [root@rancher01 ~]# docker ps -a |grep agent 2a9688d0073a rancher/agent:v1.1.2 "/run.sh https://ranc" 3 seconds ago Up 2 seconds gloomy_swirles ``` The logs make it seem that the container could connect to the Rancher Server at [https://rancher01.example.org](https://rancher01.example.org) , but then fail due to a missing URL? ``` [root@rancher01 ~]# docker logs --tail -f 2a9688d0073a Updating certificates in /etc/ssl/certs...

Steve, I did fix my issue. However, this post is from a year ago and I don’t remember how I fixed it. I suspect I deleted the Rancher Agent and all Rancher Infrastructure Containers on the host, using something like this: `docker container rm $(docker ps -a | grep rancher/ |cut -f1 -d" ")` That’s a command that I’ve used several times to help clear mysterious issues with Rancher Agent & the Infrastructure Containers. A few times I’ve even tried removing the image for the Rancher Agent. -= Stefan ---

Thanks Stefan, I think the error i am getting is different as I got different error now: from python : requests.exceptions.SSLError: [SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed (\_ssl.c:590) after some fiddling around. I am only working on a POC so will not solve this ssl problem for now. I am reverting to using http and all is good… for now.
